Applicant's summary and conclusion

Conclusions:
The test substance had an external effect in the temperature range of 220 °C - 280 °C with an energy of 14 J/g and an additional exothermal effect in the temperature range of 325 °C - 224 °C with an energy of 224 J/g.
Executive summary:

A study was conducted to determine the thermal stability of NPEO, in accordance with OECD 113. The test substance and the standard material (aluminium oxide) were heated up from ambient temperature to the final temperature (450 °C) at a constant heating rate of (3 K/min) in a defined atmosphere (nitrogen). Closed glass crucibles were used as containers for the test substance and the standard material. The quantity of the heat absorbed or released was measured and recorded. Approximately 13 mg test substance was used. The test substance had an external effect in the temperature range of 220 °C - 280 °C with an energy of 14 J/g and an additional exothermal effect in the temperature range of 325 °C - 224 °C with an energy of 224 J/g.
